对称函数环的schur -正专门化是通过参数化描述Edrei-Thoma定理的全正函数来表征的，这是一个经典的基本结果。本文研究了对称Grothendieck多项式的正专门化，即Schur多项式的k -理论变形。
It is a classical fundamental result that Schur-positive specializations of the ring of symmetric functions are characterized via totally positive functions whose parametrization describes the Edrei–Thoma theorem. In this paper, we study positive specializations of symmetric Grothendieck polynomials,K-theoretic deformations of Schur polynomials.
